Stage 4 prolapsed hemorrhoid

Hi everyone.
Six weeks ago became vegetarian. Suffered constipation for 5 weeks before reverting back to normal diet. Bowels started to move again, but 4 days ago I woke up with stage4 external/prolapsed hemorrhoid x2. Went to nurse walk in centre and told to take a lidocaine and zinc prep. This helps the pain but I am worried that the pile will not revert to normal. The nurse said they "we're pretty damn big". Any idea if they will ever go away. I am very concerned as I have been unable to leave the house for 4 days.
